论文摘要
等离子体纳米颗粒中的热电子产生是有效的等离子光催化的关键。在论文中，我们从理论上研究了tamm态（TSS）在界面金属 - 触发器上对金属纳米颗粒中热电子产生和Landau阻尼（LD）的影响。 TSS可以导致共振热电子的产生，并且LD速率提高了几次。由于金属 - 症状导体界面的介电常数的跳跃，引起的过渡吸收增强了共振热电子的产生。
The hot electron generation in plasmonic nanoparticles is the key to efficient plasmonic photocatalysis. In the paper, we study theoretically for the first time the effect of Tamm states (TSs) at the interface metal-semiconductor on hot electron generation and Landau damping (LD) in metal nanoparticles. TSs can lead to resonant hot electron generation and to the LD rate enhanced by several times. The resonant hot electron generation is reinforced by the transition absorption due to the jump of the permittivity at the metal-semiconductor interface.
